Guide looks good.
Couldn't help but notice your EU to OZ 15 amp adaptor looks to be wired in 'twin&earth' building wiring. This type of cable is for fixed installation only - not for something like a lead which flexes and moves around. The cable in your lead has a smaller count of thicker copper cores which in time will bend and break, compared to flex cables which have lots of thin copper cores.
For the sake of a small dollar amount in materials it'd be awful to see something go wrong so it might be worth getting an electrician to take a look at replacing?
