Mr Vellar and Ms Morgan were found to have engaged in "serious corrupt conduct" by the Independent Commission Against Corruption when they engineered the approval of the mammoth Quattro development on Wollongong's Flinders St.

But contained in the more than 115 exhibits tendered to ICAC are emails which show that Quattro was one of many sites the two were trading information about.

The emails expose how the pair traded privileged information, alongside flirtatious quips, on several sites across Wollongong.

In the messages, Ms Morgan uses her position to send detailed and confidential information about sites including prime beachfront land on Wollongong's Cliff Rd, property in Crown St and other prominent locations such as Fairy Meadow's Fraternity Club.

With access to aerial photographs, lot numbers, landowner details, status reports, payments, plans and maps, Ms Morgan was able to access and then leak information to Mr Vellar, who was searching for sites to develop.

The sometimes salacious emails reveal the pair was in daily contact about a range of potential development opportunities.

"Just had to say you looked absolutely outstandingly edible at lunch..!!!!!!...Oh was that DA 2003/5104 or DA 2002/1358 you wanted me to look at?", Ms Morgan said in emails in April 2005.

In the emails Ms Morgan also leaked internal staff telephone numbers and councillors' contact details, along with internal correspondence from senior council figures.

The more than 60 emails were tendered to ICAC as part of their investigation of corruption allegations into Wollongong City Council.

Ms Morgan was suspended from the council in June 2007 after an internal investigation. At the time general manager David Farmer said the council would take whatever steps were necessary to deal with any inappropriate behaviour.

"We want to stress again that Wollongong City Council is not an organisation that has or will support corruption or the perception of corruption," he said at the time.

Yesterday neither the council nor Mr Vellar, through his lawyer, would comment on the emails.

Both Mr Vellar and Ms Morgan are awaiting the third and final ICAC report due in coming months.
