I think Australia has a serious problem with national underinvestment in space. (I think the same is probably true of New Zealand as well, although I don't know as much about it, and at least with RocketLab launches New Zealand is somewhat ahead of Australia in that area.)
Australia has only had its own Space Agency since mid-2018, and its budget is minuscule (less than 10 million AUD a year.) I think Australia should aim to spend a similar percentage of GDP on civilian (non-military/non-intelligence) government space spending as the US does. Given the US economy is about 13-14 times bigger than Australia's, this would suggest ASA's annual budget ought to be around 1/13th or 1/14th of NASA's annual budget, which would be at least 100 times bigger than ASA's budget is currently. It really is an investment in the future of the country, ensuring that it doesn't get left behind.
Sorry, I was not very clear on that point, I didn't mean to imply they are doing it all in New Zealand. I meant to say that with hiring and support they get from U.S. aerospace industry (NSA, SpaceX , ULA etc) they have been able to launch out of New Zealand, for a small private country to that is remarkable and sign of lowering barriers of entry.
Rocket Lab isn't out of New Zealand, that's a popular underdog myth at this point. They're an American company, funded overwhelmingly by big US venture capital, that built their current technology primarily in the US.
The initial low scale efforts for Rocket Lab originated out of New Zealand, with sounding rockets. They moved to the US because they could go no further with the limited native aerospace and funding capabilities of New Zealand.
Their name is now Rocket Lab USA. Their headquarters has been in the US for most of their existence and progress.
And most of their efforts and expansion are now also focused in the US:

New Zealand didn't have the native aerospace engineering capabilities to build what Rocket Lab has. Most of the advanced engineering was done in California, leaning on the massive aerospace resources of the state.
