$5million is for new shares. It is is underwritten by Fosters which means they have buy any that aren't bought.
GRK current market cap is ~$10m that means that $5m will add 50% extra shares (depends on discounts etc but high level)
To put that in perspective that means that if you owned 30% of the company after the capital raising you will only own 20% (assuming you don't participate).
Essentially you will loss 33% of your stake in the company or fork up 50% of your current share holdings to maintain equivalent size share of the company.
