Not sure if this question is a troll but in the off chance it isn't here is a sample budget for the Australian government https://www.aph.gov.au/About_Parliament/Parliamentary_Depart.... It looks like the average revenue for a given year hovers a little under half a trillion dollars. So yeah they can afford it. The idea that "their coffers are empty and their balance sheet is negative" also indicates serious ignorance about how governments finance operations. I'd suggest you start with the country you currently live in and understand how your own government finances its operations. That will likely help you understand how Australia does it.
