Blue Mountains Police Rescue alone attended 900 jobs last year. I'm sure many of these were minor, but you get the idea. These factors compound quickly.

I am quite sure my maths is fine. What this is all about is to reduce the amount of contact with other people overall across the entire community.
Not sure how each of you or others are isolating, but I would be in the proximity (usually >1.5m) of dozens of people a day and for 2nd degree proximity probably 1000s (wife works in supermarket)
Personally I just go for a walk everyday for exercise, probably go to the shop for food, and get takeaway 2-3 days a week to try to support the restaurants around here.
My observations of other people in the area indicate they are probably having a lot more contacts. In the streets around this area, the parking is tight (not so much now), I know most of the regular cars which have a resident sticker. I'd say there is about a 50% or more daily turnover, i.e. a car going out and coming back or maybe not coming back and a new car coming. So with all these restrictions that people are generally obeying, people are still going to visit friends or family, visiting or staying with partners they don't live with or whatever. Shops are walking distance here. Same about the people on the beaches almost all looked >1.5m apart but there was a lot of family groups and friends together. What you have to count is what they would be doing if they weren't at the beach. Probably inside spreading germs in a enclosed space.
Going for a bushwalk and taking my own food plus most locations would not need to get fuel I would definitely encounter less people. I don't know how many people would be going bushwalking to count up to 900 police rescue jobs but could be 1 million or so. So rather than just counting the 900 police contacts, you have to count what interactions those million people would otherwise be having if they weren't bushwalking. There might be an argument about not going to remote areas, but a couple of hours from Sydney, withing a return trip for fuel shouldn't be a big deal.
I do get it that is problematic to have exceptions, but I would hope that a wider range of outdoor activities are allowed soon.
