Creek flood data was updated in 2024

When Gympie Regional Council updated its flood data on 1 January 2024, it added better detail for local catchments, including Yabba Creek (Imbil), Kandanga Creek and Amamoor Creek, alongside the Mary River. The new defined flood event allows for future climate impacts. For new habitable buildings in a flood hazard area, floors must be at the defined flood level plus 300 mm. Some major renovations to existing homes can also be caught (Gympie Regional Council – Flood information for new building work (opens in a new tab)).

Council notes that on larger lots, especially in the Rural zone, flood levels can vary across the lot. It encourages owners to contact the Building Section if a proposed dwelling would sit below the nominated level (building@gympie.qld.gov.au).

What that means for restumping: a straight restump of an existing house usually isn't affected. But if you're thinking of raising the house, adding rooms underneath or rebuilding, check the flood layers on council's mapping first and share them with your contractor and certifier.

Rural access

When you enquire, mention access for a truck and machinery (driveway length, gates, creek crossings) and whether the house is on a slope. It helps the contractor quote accurately.

Approvals

Building work on a house needs a building approval in the Gympie region, with mandatory inspections (Gympie Regional Council – Building (opens in a new tab)).
