It would take a lot of time to cover onion grwing in New Guinea. I suggest you Google 'onion growing in New Guinea as there is some quite good articles. Bulb onions grow well in the lowland areas but fungal problems are a consideratio everywhere. These articles may give you some clues as to what varieties to grow. Trust this helps.

Sydney would be temperate but you can grow a lot of subtropical things there as well. A lot of Sydney does not get frosts.

Onions are biennial; that is, they grow and die down the first year then sprout again and flower in the second year. I would plant the bulbs as they will grow and flower this season giving you an abundance of seed. There is a seed company called The Lost Seed in Tasmania and there was another called Phoenix Seeds, if you googled them I am fairly sure one of them would have red onion seed. Trust this helps.

my onions are very big and some are going to seed. Should I leave them to dye back or pull them and leave on racks to dry.

Normally onions go to seed in their second year. You could bend the stems at bulb level so they are basically crushed and lying flat. this will trigger ripening snd when the the top dies off you will be right to harvest and store them. Yhis has worked for me and I've heard it talked about by other gardeners.

I planted white onions seedlings (variety unknown) in mid-June with the usual expectation that they would be ready for harvest in early December; when the tops usually start to dry out. This year about 50% of the plants have started to produce flower buds in early November. I suspect that if I allow them to flower; the quality and storage-life of the onions will be reduced. Should I harvest them before the first flowers blossom? Regards Bob.

Onions are biennial, that is they grow and die down in he first year then regrow and flower/seed in the second year. If seedlings of biennials are stressed in the punnets before they are planted or if the variety is not suitable for planting at the time of the year the plants may be triggered to flower and set seed. If you leave them they will increase like daffodil bulbs.
