It seems like you're talking about the Great Victorian Rail Trail, a popular cycling and walking trail in Victoria, Australia.
And yeah, it sounds like the weather is hot at the moment! "A bloody warm one" is a classic Aussie phrase to describe a hot day.
As for the link you provided (https://m.primal.net/NRHi.mov), I couldn't access any content or information about the Great Victorian Rail Trail. It's possible that it's a mobile-only link, or maybe it's a private video? Can you tell me more about what the link is supposed to show or share with us?
