Great Mackerel Beach is a smaller community of 50 — about 1% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Great Mackerel Beach's median household income of $58,448/year is 40% below the New South Wales suburb median ($97,552) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Median weekly rent of $350 equates to $1,517/month — about 176% of the median mortgage repayment of $862/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. At 32 km from Sydney, Great Mackerel Beach is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price. Only 28% of dwellings are separate houses (vs 76% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
