Change Table - $40 (bunnings)
What's this? This is the cheapest change table ever! Do you mean you made one yourself, or do Bunnings sell a cheap change table?

$5000 sounds crazy! Here are some ways to save money and still buy new stuff (you can save a lot more buying on eBay etc):

Change Table from Ikea: $60
High chair / baby insert / tray from Ikea: $59
Ikea Cot plus mattress: $195
Wardrobe hangers 5 shelves from Ikea: $9
Nappy buckets from Toys R Us: $15 each
Rent-a-capsule (e.g. from QLD Ambulence): ?$60 for 6 months
Microfleece Peanut Shell Sling Carrier from babes in arms: $60

You can easily buy a decent stroller priced between $300 - $400.
