Virtually every unit of the Australian Army is different though they share a basic "on paper" structure.
The "raising of the Army" is specifically referring to the regular army and will not directly impact on reserves, other than some equipment currently in use by regular units may be "cascaded down" as newer equipment is bought to expand the regular army (which for operational and economical reasons obviously gets the "pick" of the kit).
Most units in the Australian Army that actually have a website can be found here:

Details can be gleaned on unit structure, equipment, training activities etc.
The Australian reserve is completely different as I understand it from American reserve/National Guard units. For one thing, the training budgets are hideously low, the "readiness levels" are atrocious (no Australian reserve unit is considered available for operational deployment in less than 12 months) and they use quite different equipment, vehicles etc to the regular army, because of the cost of equipping all the units.
The reserve is designed to provide an expansion base for a war of national survival. As such it does not have a high priority with Army and Government.
As an example of this, even the low level of capability provided by the current reserve armoured units with their M113A1 APC's is being stripped from them and the vehicles are being replaced by 4x4 land rovers. This is officially because the M113A1 is obsolete. Never mind that a Land Rover 4x4 is FAR LESS capable than an M113, just mind the cost of acquiring a decent and capable new vehicle...
