Humble Western Sydney dad 'blown away' after $1 million lotto win

"You're joking aren't ya?"

These were the first words of a lucky dad when he found out he'd won $1 million in Monday night's Lotto draw.

The overnight millionaire from St Clair, in Sydney's west, took home the entire division one prize in draw 4028.

The surprised winner said he couldn't wait to share the prize with his children.

"I'll take them out to dinner tonight for a bit of celebration," he said.  

"I would love to do some travel around Australia as well."

The ticket was purchased from local supermarket Foodworks St Clair.

The humble winner said he got pins and needles when he heard the news and remains in disbelief.

"I am completely blown away. I need to sit down and let this sink in," he told The Lott.

"I feel all funny now. This is incredible."

The winning numbers on November 23 were 20, 38, 35, 13, 24 and 12, while the supplementary numbers were 43 and 3.
