We do not know exactly what is going on. This species deserves more study particularly by looking at the age structure of existing populations, e.g. by looking at growth rings in toe bones. H. albopunctatus has adopted novel breeding sites, formed by roadworks or salt interceptor banks and this may partly compensate for the loss of traditional breeding sites. The known range is about 6 square kilometres. This species has a conventional breeding system.
Males call from shallow ponds and seepages in peaty swamps.
Eggs are deposited in water. Breeding activity has only been observed after a moderate intensity fire went through the main swamp in late November 1994. There is no reason to suggest fire is a stimulus to breeding but the loss of vegetation may have raised water tables sufficiently to induce water flow from seepage systems in a dry season where otherwise there might not have been any breeding. Adult frogs survived the fire in large numbers but their survival over summer is unknown. Threats to survival of this species include fire which may burn out large areas of peat, pigs, which may root up holes in the peat and destroy both breeding sites and refuge areas, and, plant diseases such as dieback which could destroy vegetation cover and radically alter the hydrology of the swamp systems.
