Singapore Airport is huge, you will fill 4 hours with no problems at all. The duty free shopping is cheaper than Australia, so best to get any alcohol or perfumes when there.
There is free internet access as well as transit lounges with comfy chairs if you just want to relax. The airport has lovely orchid gardens and water features and feels like a huge hotel.
