Possibly the same species as https://inaturalist.ala.org.au/observations/271949091 and https://inaturalist.ala.org.au/observations/270790030. Might be Monolepta abundans.

Monolepta sp. (genus)

Thanks. Great to get it ID'd - I notice only 86 records on ALA to date https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/7cb1cb11-5b6b-4571-b662-c64fbc1cfef8#overview.
Wouldn't the only other Eurispa sp. sighting on NatureMapr, from Ned Apr 2021 sighting (Eurispa sp. (genus) (Thin sedge leaf beetle)), also be the same species?

Eurispa albipennis

@Hejor1 that’s ok, hopefully someone will recognise the eggs but knowing the host plant certainly helps in most cases (someone might recognise the leaf structure though). They look like Fig Leaf Beetle (Poneridia sp.) to me but no doubt there are likely several insects that have similar egg clusters with the same shape & colouration. I don’t think we’ll get a definitive answer without the host plant or seeing the hatchlings, but I could put it in a suggestion for you & see what happens🤞😊
I’ve included an iNat link below showing similar:
