Gymea Bay infrastructure, key developments and investment opportunities

The $4 million project delivers new stairs between Ellesmere Road and the foreshore, car-park improvements and reconstruction of the shared service road, bush regeneration and landscaping, localised drainage works, improvements to the concrete pool deck and removal of an unused storage shed; the reserve will be closed while construction is carried out.

  • Is it expensive to live in Gymea Bay?

    Buying sits well above local incomes in Gymea Bay. At a median house price of $2,160,000, a house works out to about 13.6 times a typical local annual household income at the last Census, which places buying well above what people locally earned then.

    Renting a house would also take a large share of local income: $1,300 a week is about 42.7% of a typical local household's weekly income at the last Census. If you are renting rather than buying, that rent share is the figure that matters, and whether it feels expensive depends on your own income and circumstances.

    Everyone's financial situation is different, so it's important to consider your own circumstances when deciding which suburb is right for you.

  • Is Gymea Bay a good place to invest?

    The standout this year is rent growth: house rents in Gymea Bay jumped 13.0% over the past 12 months, while house values rose a solid 7.6%. Rental income has therefore increased faster than the price of houses during the year, and that relationship is the clearest signal the numbers show.

    If you're weighing Gymea Bay up as an investment, remember the value change points to capital growth over the year and the rent change points to rental income. Which of those matters more depends on your own goals and circumstances.
