My friend bought one from these guys, he is out in California so they had quick shipping to him.
I recommend buying a new one, as they are usually covered by warranty for some time

No, Spark and Mini are good beginner drones, waiting for the trade up, plus I do not think the Mini will have good sales for a while.
I would get Mavic Air because it is a step up, hope the future beginning drone flyers enjoy it though...
Wow, nice list! Covered most of the upgrades out there. I bought some of the PGYTECH Spark accessories from these guys when they were available.
PGYTECH Accessories for DJI
They do not have any other accessory brands though I have to check out the links you provided.
Wow first time I heard...
Seen these guys sell it for $12, not sure about shipping to Australia though
