Was there recently (Mon Repos in QLD, Australia), I recall them saying it was a 1 in 1000 survival rate [1, 2] which may explain why mothers are laying ~120 eggs in each clutch multiple times each season. If you head back to Mon Repos around this time of year (Feb through March) you're much more likely to see the eggs hatch.
Good news recently too, this season (2024/2025) has seen a record-breaking number of eggs being laid in Mon Repos[3]. Highly recommend anyone goes visit, pretty special.
