May I please ask if the external degree in Bachelor of Laws (external LLB) awarded by University of Staffordshire (SU) from United Kingdom (UK) is recognised by the Legal Practise Board of Western Australia (LPBWA) for practice as a lawyer in Western Australia (WA)? 

Are there any prerequisite requirements or conditions (class of honours degree obtained, minimum number of years of study, etc) which have to be satisfied before the SU external LLB is recognised for practice as a lawyer by Australia or the LPBWA?

If the SU external LLB is recognised, how is the typical procedure like for such a graduate who wishes to practise as a lawyer in Australia?

May I please request for further details and information regarding these issues?

Thanks alot for all the assistance and advice.

You'd need to contact the legal practice board ask them. You'd most likely need to get your degree evaluated by them. 

There would also most likely be a practical legal training requirement (PLT), as well.
