Then there is the little question of fixing, and recording, you position every half hour as required by VFR regs...
What regs require you to record your position every half an hour?
Do you mean
ENR 1.1 19.2.1
b)When navigating by visual reference to the ground or water, the pilot in command must positively fix the aircraft's position by visual reference to features shown on topographical charts at intervals not exceeding 30 minutes.
Fix your position, yes. No one says you have to pick up a pen and write it down, do they?

CAR 78 Navigation logs

79 Form of logs
(1) A log kept under this Part shall be kept in accordance with such form, and in such manner, as CASA directs.
Yes, you need to keep a navigation log so you always know where you are. Nothing says this log must be written on paper.
