On 5 September 2013 the ACCC announced it will not oppose the proposed acquisition of Karrinyup Shopping Centre (Karrinyup) by the Westfield Group and Westfield Retail Trust (together, Westfield).  Westfield currently has a 33% interest in Karrinyup.

ACCC’s non-opposition was subject to Westfield’s undertaking to divest its ownership of Westfield Innaloo (a sub-regional shopping centre located 3.3 kilometres from Karrinyup) to a purchaser approved by the ACCC if the proposed acquisition proceeds.
