Australian dates in access

Hey all,

I have a control box in my form that asks the user to enter a date. It then
takes the date and turns it into the default date so that it will show up on
the next record. It accepts the date and saves it to the table in the
correct format (dd/mm/yyyy) but then when it copies it over to the next form
it converts the date into american format (mm/dd/yyyy). I have worked out it
must be something to do with the code. This is what I currently have in the
relevant section of coding.

Private Sub DateFirstSession_AfterUpdate()
DateFirstSession.DefaultValue = "#" & DateFirstSession.Value & "#"
End Sub

Any assistance as to how I should code it so that it accepts the correct
date format would be greatly appreciated. I have my regional settings in
Windows correctly set to Australia and am using Access 2003.
