A question for our gardeners: if I put bird netting (mesh size 5mm ) over the veggie garden at the beginning of the season, will it be a problem for pollination?

For crops pollinated by bees - eg cucurbits - yes. For wind/vibration pollinated crops - no.
5mm is actually hail netting.

Fruit trees, berries, okra and all cucurbits need insects (preferably bees) or can be pollinated by hand. Broad beans seem to set better with bees but not essential.
Everything else is wind/vibration. If you want to keep your own seed from carrots and parsnips - they set more with insects - even little flies or ants will do.
worth mentioning that in less windy areas fine net/shade cloth may cut down the amount of wind bumping plants around and may decrease fruit set. Every morning and evening I go around with a 60cm length of 10mm dowel and tap tomato trellises in the greenhouse as well as tickling flowers on non-trellis plants (capsicums and eggplant) because without any wind to shake them around they don't set fruit.

Thanks for the tips spinifex, much appreciated.

Holy cow! What state? I assume its to do with wildlife/pet safety? Must look that up to see if that applies to commercial growers too.
I made the mistake of allowing a lot of loose net to flop around on the ground around one of my Boysenberry trellises and was dismayed to find a pair of blue tounge lizards tangled and dead one day. About a week after the lizards I found a honey eater and a blue wren tangled. At that point I re-jigged the setup so all the net was pulled tight and the loose ends all rolled up and pinned to the ground with planks. No more entanglements after that.
I get my bird net direct from industry suppliers - the stuff with a 20 year lifespan. Need a good frame to hold it up because its quite heavy.
