Hi,

This type of insect is frequently found trapped in our backyard pool, NSW, Australia. Can you please help and identify it?

I can't say what species but I would call this a "mole cricket" - some info on the family (Gryllotalpidae) here

That said, a couple of my Australian colleagues said they would call cooloquially call this a "sandgroper", although that common name seems now to be associated with species now assigned to the family Cylindrachetidae

Both these families are  part of the order Orthoptera which includes grasshoppers, crickets, locusts and their close relatives.
