Early results and feedback from retailers are "fantastic" and the system is working fine with no technical issues to report, he says, unlike last year when Click Frenzy IT systems went into meltdown, unable to cope with traffic volumes.
There have been over 1 million visits to the participating retailers, by 7am this morning. The three most popular are Big W, Myer and Bonds.
Click Frenzy sites have already been visited by 580,000 consumers mostly in the first 12 hours, suggesting consumers are hitting multiple retailers looking for deals. There are 300 brands and retailers in total, an increase from last year.
"We are ecstatic with the results from last night and set for a massive second half today as it's far from over," says Arnott.
"At the same point last year, I wanted to crawl into a hole, so for the whole team at Click Frenzy and our technology and marketing partners, this is a great feeling."
Consumer activity on Click Frenzy is a lot more "frentic" this year - it's less about curiosity and more about grabbing bargains, says Arnott.
"Everyone is hungry for deals". Womenswear, toys and electrical are the most sought after items so far.
Bargain hungry consumers too seem to be pleased with this year's event, judging by Twitter comments.
Average time spent online by "frentic" shoppers is 10 minutes. The average number of pages visited is 7.5.
