I had a 2015 TDI with exactly the same issue! Starts fine cold starts at home park at work for the day then start it up again and it idles rough and shakes for about 10 seconds. The issue itself was worse if the ambient temperature was above 30C and the engine was cold.

I replaced the air filter fuel filter make no difference. I ended up removing all the throttle bodies and discovering everything was caked in Carbon and Oil mixture inside, you could only get 2 fingers inside. I removed the entire air intake system and ended up cleaning all the backs of the valves removed all the oily carbon residue. To slow this down from happening again I fitted an oil catch can inline with the turbo. All the blowby oil comes out of the top of the engine then is sucked into the turbo (Pools at the lower part of the intercooler!) then the rest makes it way up to both of the throttle bodies where it mixes with the EGR exhaust gasses.

Doing all of this should fix this issue! I also live in Australia.
