Hi Russel
I'm in New Zealand.
I see. You are effectively operating from the back of the machine instead of the front and everything is reversed to standard. It you rotate your piece of paper 180 degrees you will see how it should be.
I would personally set the machine up as it should be as it will not affect the Gcode you currently have and the screen will reflect what you see on the table instead of everything being upside down when you cut your projects, but it is up to you.
If the axis are not running in the direction that you want then go into the X or Y axis settings and check or uncheck the invert direction box and the axis will reverse direction.
This video might help explain.
Cheers Peter
