Hi folks

Aussie bloke it means

'Goodbye and may the road go with you'

Tuigean tu? (Do you understand?)

May the road go with you is isimilar to another which is

Go n'eiri an bothar leat (May the road rise to meet you)

Both of these simply mean may the path that lies ahead of you be easy and wothout trouble

Hope this helps

Lig do sath (Take it easy)
