The state and national rules. TPB registration, the client information requirements under the 2024 Code determination and WA payroll tax work the same way in Mandurah as in the capital, and our Perth accountants page sets them out with sources. What follows is what's particular to Mandurah.
An older city. The ABS counted 90,306 people in the City of Mandurah at the 2021 Census. The median age was 45, against 38 for WA and Australia, and 25.5% of residents were 65 or over, compared with 16.1% statewide. A third of occupied homes (33.6%) were owned outright, above the WA figure of 29.2%. That shapes a practice's work: more returns with super income streams and investment property, more estates, and more people thinking about selling the family home. The ATO says that from age 55 a person may be able to put up to $300,000 from the sale of their home into super as a downsizer contribution. A practice that helps with the tax side can say so and link to the ATO, but any recommendation about super is financial product advice, so the website wording should match what you're licensed to give.
Mines and refineries. At the same Census, 4.1% of employed Mandurah residents worked in iron ore mining, against 2.9% across WA and 0.4% nationally. Western Australia's iron ore is mined far to the north, so many of those residents are likely to work away from home on a roster. Another 3.0% worked in alumina production, against 0.3% across WA, which in the Peel means Alcoa's Pinjarra refinery. Technicians and trades workers (18.6%) and machinery operators and drivers (10.9%) both made up more of the workforce than the state average. If these people are a large share of your clients, a page that covers rosters, allowances and site deductions, and explains how to book from a camp, will do more than a general 'individual tax' heading.
A small-operator economy. ABS business counts show the City of Mandurah grew from 4,439 businesses in June 2021 to 5,199 in June 2025. Construction remains the largest group at 1,247, transport, postal and warehousing rose from 340 to 405, and health care and social assistance rose from 322 to 430, which covers the support workers and allied health clinics growing with an older population. Only 144 businesses employed 20 or more people. A practice here mostly serves owner-operators, so a short, plain list of what's included in a BAS or year-end package is worth more than a page about corporate advisory.
Working with us. We're an Adelaide team and work with Peel practices by phone and email; we don't visit Mandurah.
