Heading from Sydney to Melbourne it's often advantageous to fly relatively low (FL280 or so). That's around the 'crossover' point where we switch from IAS to mach, so it is often around that altitude that you'll achieve the best TAS. Additionally, it's often below the strongest winds, so G/S is also as good as you'll get it.
Going from Melbourne to Sydney, it's generally better to climb to the high 30s.
whats the benefit of Mach over IAS?
