Obviously your place is frog –friendly. These animals may be recent recruits to the population following February large rain events. They can breed from about October to March. We have now had two good summers in a row for suitable breeding of frogs like the ones at your place. Large breeding events like these sustains the population through years of drought when no breeding occurs. Brundee Swamp Nature Reserve (eastern end of Boston Rd) is one of the most important sites in the Shoalhaven for conserving the habitat and populations of Green and Golden Bell Frog. Following metamorphosis into frogs from tadpoles these animals may have dispersed along drainages and grassy corridors from their site of breeding to your place. Alternatively they may have bred in nearby ponds or waterholes or even at your place if you have a pond or two. In dry years you may not see them. The GGBF is unusual in that it likes to bask in the sun during the day (mornings), that is why they are readily observable, so sunny spots are good too. Try and maintain some moist, dark/shady areas in your garden where they can hide and survive dry spells, winter and drought.
Call into our office for a GGBF brochure with more info or phone and a brochure can be posted to you.

This species was the mascot for the Sydney 2000 Olympic Games as there is a wild population at Homebush Olympic park.
