Treasury not happy with Morrison, page-2

OK, the 2020 election is almost certainly going to feature 2 POTUS candidates who back looser fiscal policy, easier monetary policy, a weak USD and trade protectionism.
The question for Aussie treasury is - of exactly what it is a country/region depends on RoW for. a) financing b) technology c) markets. Proceeding from there, is the loss of any of those substitutable domestically and at what cost. Are the constraints on that substitution economic or political?
For RBA - see government bond market and financing (KOO's economics). 
Can't comment much on Aussie elections, I haven't been following Aussie politics since out of the country (a few years).
