I am trying to find the phone number and address of Unified
Interactive.  I know that it is in Westlake, Australia.  Past phone
number 61 7 33763332 is disconected.

Considering the legal problems that this firm has had, it is entirely
possible that the company has folded.

kathydelhi,
I fear no phone number is available for the entity requested. 

It appears ?Unified Interactive? (assumed to be Unified Interactive
Pty Ltd A.C.N. 079 956 531 (1), A.B.N. 87 079 956 531 (2)) is the
Australian end of a multi-jurisdictional web scam, presently being
prosecuted before the Australian Federal Court by the A.C.C.C. (3).
See article here:

If this entity is the one sought by you I can confirm that on paper
they still exist (from check of the Australian registry of corporate
and business names (i.e. A.S.I.C)(4)) but as they are named in the
action (from check of Federal Court Records (5)) their continued
existence is doubtful at best.

Notes:
(1) Australian Company Number: An identifier number for companies.
(2) Australian Business Number: An identifier number for businesses. 
(3) Australian Competition and Consumer Commission: who are the
equivalent of the American ?Securities & Exchange Commission (S.E.C.)?
or corporate watchdogs that act in the public interest, when nefarious
and improper actions are committed.
(4) Australian Securities & Investment Commission. For search see here:
