Banksia Beach is the newer end of Bribie Island, taking in the Pacific Harbour canal estate and the golf course, with homes built from the 1990s onward. The houses are larger than elsewhere on the island and the systems are younger.

Larger homes on a coastal island
Sizing is the first consideration. Houses here commonly run two or more bathrooms, and a system sized for the original household may not suit the one living there now. Allow roughly 50 litres of storage per person per day for electric, or size continuous flow by how many outlets run at once.
Salt air is the second, and it applies even on the canal side. External units, valves and fittings corrode faster than inland, so placement out of direct exposure and a model with good corrosion protection both matter.
Mains natural gas is not the norm across the island, so the realistic options are electric storage, LPG or a heat pump. These blocks have room to place a heat pump with airflow and away from bedroom windows, which makes it a sensible upgrade when an electric tank fails.
Costs, from swap to upgrade
A like-for-like electric storage swap runs from around $800 to $2,500 installed, with larger tanks at the upper end. Gas storage and continuous flow sit around $1,200 to $3,500 installed where gas is connected. Repairs on younger systems run roughly $150 to $600 depending on the part. Heat pumps run around $3,000 to $6,000 installed before incentives, with federal certificates reducing the net installed price on eligible models.
Frequently asked questions
Does a canal block get as much salt as the surf side?
Less direct spray, but the air is still salt-laden. Placement out of the prevailing wind and corrosion-resistant fittings are still worth specifying.
Our estate has body corporate rules. Does that affect a replacement?
It can, where the unit is visible or sits outside your lot boundary. Check the by-laws and let the manager know before the work is booked.
