Thanks guys for your input.
Signed up with Affinity Insurance brokers now (CGU underwritten).
Cost me $40 more than the Allianz but have now additional $3000 camping gear cover build in and a few more little extras which Allianz didn't have.
The KJ is insured for market value with $7000 of extras (lift kit, bull bar and and and). Insured on any track/place anywhere in oz. Total annual cost $1071.00. Plus they didn't blink at the 2.75 inch lift kit and the bigger tires.
