Bridging Visas  

Hello,

I understand that bridging visas are issued for people waiting for a decision to move from one substantive visa to another if the former runs out. However, I am not sure what denotes a substantive visa.

I am particularly interested in moving from:

Second Working Holiday Visa to a Third Working Holiday Visa

Third Working Holiday Visa to a 476 Recognised skilled graduate visa

and finally, the 476 skilled graduate while waiting for a 189 application.

Would just like to know if a bridging visa would be issued for any of these transitions or where I can find the information on substantive visas...

Thanks for any help :)

Jim
