Military budgets in most western countries are extremely well devised, as it's a sort of pivotal point on any country. It ensures that every aspect of ones land is protected efficiently against any type of attack, terrorism, espionage, assassinations, sabotage from any country that is deemed to be a threat. And they have to have offensive forces to look after the countries interests.
That depends on the nation, some of that legally might or would have to be done by police forces, mind.

For example, if Japan uses their armed forces for anything BUT defence, that is grounds for the entire UN, and anyone else who might want to join in to declare open war on them instantly.
Not true, they sent forces to Iraq, IIRC. They had to change the rules to do this, mind.

In Australia, we really need to increase our budget up to about 30bil at the least, considering if the US ever drops support we would be invaded by another close country faster than you could fucking blink, and when we have a military force large enough to defend MAYBE 1 of our states, you know there's a problem.
If it was a small scale war, we would easily win. Our training and equipment is some of the best in the world. But we would lose very, very badly if a full scale invasion happened.
Firstly, yes, the close ties with the US is one of the reasons the ADF isn't bigger than it is.
But, putting the US aside for a moment, who is going to invade Australia? What military has the logistical capability to defeat Australia and its remaining allies (including the UK)? Not merely the raw numbers of troops, the tankers and transport vehicles to get an invasion force all the way to Australia's coastline, form a bridgehead, and push inland? Troop numbers are utterly irrelevant if they can't be deployed and equipped where you need them to be. Likewise, China simply can't flood the US with troops and rely on numbers because there's an ocean in the way, and China doesn't have a navy anywhere big enough for the task.
Anyway, once you get to Australia, of course, you've still got far too much territory to take and hold. Even if you ignore anything that isn't a major city, the distance between Sydney and Melbourne is the length of Italy.

Australia can be threatened by, for example, India. Using NOTHING other than their planes, they could take our country. The Su-30 is a decent match for our F/A-18s. India has 150 of them. We have 70 F-18s, meaning we'd have to take out 3 for every 1 plane lost and THEN start on the MiG-29s. They would clear our skies within a few hours and then send their bombers in, before we admit defeat and give the our country within a week.
The distance from India to Australia is about 7,200 km. The effective range of a Su-30 is about 5,000km.
Also, and very importantly, there's no reason for India to attack Australia. If it wanted to conquer someone, there's plenty of better targets. And there's no advantage to doing so anyway.
Australia isn't at risk of invasion because, on top of anything else, there's no reason for anyone to want to invade it.
EDIT: The distances are from centre of India to centre of Australia, it seems. The Indian Su-30, with mid-flight refueling, might be able to run out of fuel and crash in the northern territory.
