Yes, Splodge, you want a reverse cycle, multi split unit. Look for ones that have the quietest outdoor and indoor units and the most energy rating stars. From my quick look online, that's Daikin or Mitsubishi. I'm inclined to go the Mitsubishi because they use a refrigerant with a lower ozone depleting potential (that means it's slightly better for the environment)
You need about 3.5kw indoor unit in your study and 3kw in your bedroom. I imagine the outdoor unit would be installed in the walkway on the east side of your house, near your bedroom window and the place you would install the indoor units. That's why choosing a quiet outdoor unit is important. The indoor units would also be easiest to install on the outside wall.
If you're going to the effort of putting them in, it would be a minor cost to increase the size of the outdoor unit slightly and install one in the lounge room too. Even if you wanted to wait until you pull down the wall between the lounge and kitchen, you could buy an outdoor unit that will do them all and install the indoor unit later. That way you would have heating through all of your living areas. You don't need to heat the hallway. On the other hand, just a gas heater (ie no cooling) in the kitchen/loungeroom would incur lower operating and greenhouse costs - if you don't have cooling there, you won't use cooling there.
The links below are for brochures from Sustainability Victoria and include advice on choosing heating and cooling systems. I really like the graphs at the end which compare running costs for the different options. The heating one also compares CO2 emissions.
Choosing a reverse cycle air conditioner
Choosing a cooling system
and, because you're talking about using it for heating too, Choosing a heating system
btw, if you want info on having an energy efficient home and appliances, I really like Sustainability Victoria and the greenhouse office's technical manual for home design - they're my first stop when I just want an introduction to some of the issues to consider.
And, for the sake of completeness/ my conscience, also from the Sustainability Victoria website, Melbourne needs cooling as often as Brisbane needs heating - would you install a permanent heater in Brisbane?
