Founder Guide · Updated 18 May 2026
Practical, action-ordered and AU-specific. Covers niche selection, ABN and GST, Cert III/IV qualifications, AUSactive registration, premises, insurance, equipment, pricing and landing your first 50 members.
The fitness industry isn't one market — it's at least six. Each has different break-even economics, customer types and equipment costs. Picking the niche before you sign a lease or buy gear matters more than people realise — the same operator can't credibly run a 24/7 gym, mobile PT and online coaching with one playbook.
24/7 / staffed gym
Highest capital, highest revenue ceiling. Lease, equipment, $100k+ fit-out.
Boutique studio
Single-discipline (HIIT, F45-style, spin, reformer). $30–80k fit-out, premium pricing.
Personal training studio
Small-footprint PT-only space. Lower lease, members pay for 1:1.
Mobile / outdoor PT
Park, beach, home visits. Lowest capital — ABN, kit, insurance and go.
Online coaching
Remote programming. Highest scale potential, lowest physical capital.
Yoga / Pilates studio
Reformer beds, mats, sprung floor. Mid-capital with strong membership retention.
An Australian Business Number (ABN) is mandatory to issue tax invoices and is the prerequisite for almost everything else — bank accounts, GST, supplier accounts, insurance. ABN registration is free, takes 15 minutes online, and you get the number instantly.
Sole trader
Cheapest, simplest. Personal liability — paired with strong insurance + waivers.
Pty Ltd
Limited liability. Setup ~$500, annual ASIC fee ~$300. Worth it once turnover >$100k or you have premises.
Trust + corporate trustee
For multi-site or family-asset structures. Get accounting advice before incorporating.
GST threshold $75,000
Mandatory registration once annual turnover hits or is expected to hit $75k.
BAS frequency quarterly
Standard for most operators. Monthly only required if turnover >$20m.
You need a recognised fitness qualification before you can legally instruct in a regulated way and before any insurer will write you professional indemnity. Cert III is the minimum for group fitness; Cert IV for one-to-one PT. AUSactive (formerly Fitness Australia) registration is voluntary nationally but the de facto industry standard.
Cert III in Fitness (SIS30321)
Minimum for gym instruction and group fitness. ~6 months part-time at a recognised RTO.
Cert IV in Fitness (SIS40221)
Required for one-to-one personal training. Adds program design and exercise prescription.
First-aid + CPR
Current first-aid certificate and annual CPR refresher — mandatory for AUSactive registration.
AUSactive Exercise Professional registration
Voluntary national registration. Required by most insurance schemes and corporate wellness panels.
AUSactive Business Member
Business-level registration. Quality endorsement plus group buying on insurance.
Specialist certs (Pilates, yoga, S&C)
Discipline-specific certifications beyond Cert IV — Polestar Pilates, RYT-200/500 yoga, ASCA strength & conditioning.
If you're running a 24/7 gym, boutique studio or PT studio, premises is your single biggest line item. Zoning, change-of-use approvals, Disability Discrimination Act access, parking and lease terms all affect viability. Mobile and online operators skip this step but should still register a principal place of business.
Council zoning
Most fitness uses sit under 'recreation facility' or 'health and fitness centre' zoning. Confirm before signing a lease.
Change of use
Converting a warehouse, office or retail to a gym typically requires a development application — 4–12 weeks.
DDA compliance
Access for members with disability under the Disability Discrimination Act — ramps, accessible toilets, lift access if multi-level.
Acoustic and structural
Strength training drops noise transmits to neighbours. Sprung or rubberised floors plus acoustic insulation often required by lease or strata.
Lease length and break clauses
5+1+1 typical for fitness. Negotiate break clauses for non-performance and rent reviews tied to CPI not market.
Parking and shower facilities
Member-experience non-negotiables for 24/7 and boutique formats. Pre-build assessment beats post-fit-out retrofit.
Public liability protects you when something goes wrong on the floor or in a class. PT professional indemnity protects you when a member alleges injury from a program or exercise prescription. Workers compensation applies the moment you have an employee — including casuals.
Public liability $10–20m
Standard floor for residential / member-facing. $20m minimum for commercial-wellness panels.
PT professional indemnity
Separate policy covering exercise prescription, programming and nutrition advice within scope. Cheaper through AUSactive group scheme.
Workers compensation
State-specific scheme. Compulsory for any employer. Premium based on payroll.
Tools and equipment
Cover for equipment, reformers, treadmills, free weights — replacement value, not depreciated.
Premises and contents
Building (if owner), contents, glass, signage. Bundle with business interruption.
Cyber liability
Membership databases hold health information — data-breach exposure under the Privacy Act and Notifiable Data Breaches scheme.
Equipment cost varies wildly by format — a mobile PT can start under $1,500; a 200-square-metre boutique studio is $40–100k; a 24/7 fitness centre is $150k+. The bigger spend hides in the management platform you choose for bookings, member billing, class scheduling and door access.
Mobile PT kit
Suspension trainer, resistance bands, kettlebells, mat, BP cuff. ~$1,500. Fits in a car.
Boutique studio fit-out
Sprung floor, mirrors, sound system, format-specific equipment (HIIT rigs, reformers, spin bikes). $30–80k.
24/7 gym fit-out
Cardio bank, strength rack, free weights, machines, door access, CCTV, member-only access. $100k+.
Yoga / Pilates
Reformer beds ($2.5–6k each), wall units, props, mats, sprung floor. $30–60k for a 10-bed studio.
Class & member platform
Bookings, recurring billing, class waitlists, member app, door integration. Recurring monthly cost — pick well.
Body composition / wellness tech
InBody scanner, BP/HR monitors, wearables sync. Optional but converts initial assessments to paid programs.
Pricing fitness is about the lifetime value of a member, not the cost of a single session. Casual rates, pack discounts, membership tiers and class-pass economics all interact. Use the OneBookPlus session pricing calculator to model break-even members against fixed costs.
Casual session $80–120
1:1 PT casual rate. Anchors the value perception of multi-session packs.
10-pack discount 10–20%
Standard pack discount on 1:1 PT — locks in commitment without devaluing.
Membership $20–80/week
Boutique HIIT / spin / yoga in the $40–60 range. 24/7 gym at $15–25. Reformer Pilates $50–80.
Target margin 60%+
Gross margin on class formats before fixed costs. 24/7 gyms run higher; PT-heavy studios slightly lower.
Founding-member offer
12-week locked-in rate for first 50 members. Avoids lifetime discounts and signals momentum.
The first 50 members are the hardest because you have no social proof. Lean on local marketing, founding-member packages, community partnerships and online review compounding. Don't over-discount in perpetuity — a cheap reputation is hard to shake.
Founding 50 campaign
First 50 members at a locked-in lower rate for 12 weeks, in exchange for testimonials and reviews.
Google Business Profile
Free. Reviews compound. Show up on Maps for 'gym near me' or 'pilates [suburb]'.
Local Instagram + reels
Member transformations (with consent), behind-the-scenes, free 7-day trial CTA. Daily cadence beats production polish.
Free open-week
Two weeks of free classes pre-launch builds list and converts trialists at 30–40%.
Corporate wellness
Reach out to local businesses for staff packages. Higher LTV, lower churn than retail members.
Community partnerships
Cafes, allied health, physiotherapists, sportswear retailers. Cross-refer in both directions.
What goes wrong
Most failed fitness businesses lock into a lease that needs 200+ members at full rate to break even, then run out of cash before they get there. Model fixed costs against realistic member-acquisition timelines.
Per-class rates for group fitness instructors must include preparation time (typically a 1.25× hourly equivalent). Operators who quote the bare hourly rate underpay and rack up back-pay liability.
Every member should complete a pre-exercise screening (PAR-Q+) and sign a participation waiver before training. Insurers will not pay out a member-injury claim where the waiver and screening weren't completed.
PT chair-rent arrangements only stand up if the PT genuinely runs their own business. Fair Work has re-characterised many fitness PT arrangements as employment with significant back-pay, super and leave liability.
The single most common ACL breach in fitness — a member cancels, the debit keeps running. State regulators (NSW, VIC) publish enforcement actions monthly. A documented cancellation pathway is your defence.
Acquisition cost is 5–10× retention cost. Most operators obsess over Instagram ads and ignore member onboarding. A structured 30/60/90-day onboarding sequence improves retention more than any acquisition spend.
Run 4–8 weeks of pop-up classes (park, hired hall, partner studio) before committing to a lease. The pop-up phase validates demand at price, builds a waiting list and gives you real conversion data — not assumptions.
A studio losing 8% of members per month needs to acquire 8% per month just to stand still. A studio losing 4% per month doubles in size with the same acquisition effort. Onboarding sequences, check-ins at day 30/60/90, and community events drive retention more than discounts.
Health information (injuries, conditions, PAR-Q+) collected as part of fitness onboarding falls under the Privacy Act. Storage, access controls and the Notifiable Data Breaches scheme apply. A SaaS platform with role-based access beats a shared Google Drive folder every time.
Hiring your first casual class instructor triggers workers comp registration, casual loading on every shift, award-rate compliance, payroll setup and SuperStream. Plan the cash-flow impact at least 8 weeks before the first shift — and make the first hire someone you've already trialled as a sub.
Mobile PT: $3,000–$8,000 (Cert IV + kit + insurance + ABN + marketing). PT studio: $30,000–$80,000 (lease bond + fit-out + equipment). Boutique HIIT/spin/yoga studio: $80,000–$200,000. Full 24/7 fitness centre: $200,000–$600,000+ depending on size and equipment grade. The biggest swing factors are lease (bond + fit-out) and equipment.
If you're instructing members in any capacity (group fitness, gym floor, PT), you need at least Cert III in Fitness. For one-to-one PT, you need Cert IV. If you're running a fitness business as the owner-operator without instructing personally (e.g., owning a 24/7 gym staffed by qualified instructors), you don't personally need the qualification — your instructors do.
Not legally — AUSactive Business Member registration is voluntary nationally. However, most professional indemnity insurers offer significantly cheaper premiums through the AUSactive group scheme, most corporate wellness panels require it, and parents booking junior programs check for it. It's typically the highest-ROI annual spend after insurance.
Mobile PT can be cash-positive within 3 months (low fixed costs). A studio typically takes 12–24 months to hit break-even at 60–80% capacity. A 24/7 fitness centre is 18–36 months to profitability. The key driver is member retention — a studio at 80% capacity with 4% monthly churn is profitable; the same studio at 8% monthly churn is bleeding.
Mobile PT and online coaching work well part-time — 6am, lunchtime and evening sessions plus weekends fit around a 9-5. Studio and gym models do not — they need daily owner presence. Most full-time fitness operators start as side-hustle PTs to build a client base, then transition once book is full.
Mobile PT can scale to ~$120k revenue solo. To go beyond that you either hire (Level 3+ instructors under the Fitness Industry Award) or shift to a digital/online model. Most operators hire their first casual class instructor at around the $80k revenue mark. Workers comp + casual loading + award-rate compliance kicks in the moment you hire — plan the jump carefully.
