I got this through the What's On Olympic Park email - it's free to join for those interested (http://www.sydneyolympicpark.com.au/whats_on/members_area/re…). It's not an offer for the masses, but might be useful for someone out there.
The offer:
What's On? members can enjoy 50% of Apia International Sydney family passes to tennis sessions from Sunday 6 January- Friday 11 January 2013, for Ken Rosewall Arena (Centre Court) sessions 1 - 8. Offer excludes women and mens finals. Offer does not apply to ground passes.

Call 1300 888 104, select Apia International Sydney at the prompt and state that you are a What's On member.
