Bellbird automotive services overall is a good place to come to if you're in need of a car battery or tyre change. They can be a bit pricey compared to others but still are friendly and do the job in good time. Recommend you get a quote first.
I can highly recommend Smart Torque! These guys went out of there way to get me and my 3 year old up and back on the road. We were travelling from Victoria, when just out of Sydney, our D40 Navara developed a serious issue with suddenly going into limp mode. Towing a 21 foot caravan, this is seriously dangerous, when we couldn't exceed 40 kms going up hill on the freeway! Called Smart Torque and told them of our problem, they said come around right now and we will sort it. The mechanics did a thorough inspection of the car, and not happy to just chuck this in and see how she goes mate they performed numerous test drives, and diagnosed the actual problem. Part was ordered, and I had the car back by lunch time the next day. Running like a dream, and my stress levels now back down to normal! Thanks guys, cant recommend highly enough!
