Sydney Olympic Park is where the 2000 (yes, it was over 10 years ago now) Olympics were headquartered. Sitting alongside the Parramatta River, much of it had been used for "dirty" (or relatively dirty) industries for many years, but was rehabilitated as parkland (the adjoining Bicentennial Park), sporting and event facilities or commercial / residential complexes.

The brickpit, as the name suggests, was a quarry from which material was extracted for brick manufacture until it closed in 1992. The end of quarrying left extensive freshwater wetlands which, by 1993, had become home to a large population of Green and Golden Bell Frogs. Rather than develop the brickpit as a sporting venue, it was decided to leave it as a frog habitat.

The ringwalk provides viewing access to the old brickpit. It stands 18 metres above the brickpit floor, and signs caution visitors with vertigo not to venture on it... with good reason, especially as it sways in high winds. There was little chance of that this morning, though, as it was a still Sydney Summer's morning, heading to a high of around 32 degrees in this part of the world. (Dammit.)
