Question re roadworthy requirements

[sednwol]

As you can see from my previous post I am looking at getting another AU and have had an RACV test which has found several issues some listed below. Are these items covered by a roadworthy and repairable by the dealer?

Exhaust system: corroded and leaking.
Panels: front bumper bar not fully secured.
Underbody: splash shields not fitted on front.
LPG, not sealed.

Its a thirteen year old car with 245000Kms and has oil leaking (moderate)from sump, timing case, flywheel housing areas. Oil weeping steering rack.
