There is only one PT team at the men's edition.
I was more thinking about the other two with a wildcard guarantee not coming, as is basically the case every year. Q36.5 has their guys in the national team anyway, but I guess a team like Cofidis would normally be interested, if everything was paid for them - also because the sprint race afterwards is now 1.pro.
By UCI rules, ProTeams only need to be paid 3500 EUR for travel exposures (+hotel costs, of course), while the mimimum participation allowance for WT teams comes down to a PCC agreement. And for 3500 Euro, obviously no one can travel to Australia.
So while all three PT teams must still be invited, an overseas race could basically cherry pick by offering one more than the other.
So it would be interesting to know how exactly this is handled.
