The former accountant from Redcliffe is aware of the risks but has weighed up the opportunity as a buy.

This is the last day for retail investors to apply for shares and institutional applicants have until next Friday.

The offer is being pitched at a range of $2.50 to $3, implying a market capitalisation on issue at these prices of between $6.1 billion and $7.3 billion across 2.4 billion shares.

"I have applied for $20,000 in my name and $20,000 in the name of my self-managed super fund with my husband Alan," Ms Kenrick said, adding her husband "doesn't want to touch it after the Myer float".

Ms Kenrick first dabbled in equities during the early 1990s, buying Commonwealth Bank and Woolworths shares, which have enjoyed stellar price rises.

"I get a bit bogged down with reading the prospectus but RBS Morgans gave its clients some good research summary, which included both the positive and negative points," said the 57-year-old, who retired 18 months ago.

"My view is, you have got to invest in something. I take calculated risks, you don't just go and chuck it all on a horse.

"I have good core stocks and then I dabble on the side with things like Tissue Therapies, which is really paying off for me and Macarthur Coal, which were seen as a risk when I bought them for $1 each."

Ms Kenrick said every share buy was risky, but believed QR was a better bet than most because the inefficiencies of the government-owned operation would be rapidly ironed out in the private sector.

The issue has not been without debate in the Kenrick household.

She said her husband was of the attitude that share prices typically drop after an IPO, but on QR, Ms Kenrick disagreed.

"I think it'll be priced well, so the Government gets its money and everyone stays happy.

"I really do think this is a growth stock and with my super fund, I tend to buy more for income and dividends but in my own name, I buy for growth, I play."

Ms Kenrick boasts her own portfolio brings in superior profits to her husband's.

Showing a healthy appetite for risk, Ms Kenrick bought more shares after the Myer price dropped but the move has paid off with those shares now making a gain.

"Our portfolios are totally different but overall my returns are higher than his."
