[VIC] Wanting to do first oil change 2019 Golf R, where to buy all the parts?

[bkpr]

Hey all. Where do y'all buy all the things needed for an oil change? I'm wanting to do my own interim changes, so I need the filter + o-ring, new drain plug, and 6L of oil (I can research which oil I need and find it somewhere locally I expect). Is it best to go to a genuine VW dealer for these things or is there somewhere local/online I can order from? I'm on the Mornington Peninsula in Victoria.

Thanks in advance!
