If you can find a merida e140/160 , they are awesome bikes and one of the best value bikes n the aus market. Warranty from merida is less than their other investment company ( they own a lot of specialized) , but the geometry is REALY nice - not quite as nimble as my levo sl but still VERY capable. Reasonably light for a full power emtb , and great spec for the price. One of the guys I regularly ride with bought an e160 8000 , awesome bike.
If there is any way you can justify keeping the giant as a commuter AND buying a merida, that would be the smartest choice. Back in my uni days I tried the road trail motorbike thing - weekdays flogging a dirt bike through traffic, weekends slithering through the bush, spare time spent changing tyres / desperately repairing damage sunday evenings / monday am.....it doesn't work well. Plus you get tempted to commute on dirt rubber - unsafe and expensive to shred, or worse still dirt ride on commuting rubber ( hospitals are busy at the moment)
Worst case scenario, you get hooked on emtb and have to fund an expensive hobby - you have been warned
