NAB SPP Risks, page-31

I think the SPP will be massively oversubscribed and that most retail investors will be very disappointed with their allocations.
NAB market cap is approx $50b and SPP is only $500m.
A quick look at last years annual report:
There were 333,000 small shareholders with less than 1000 shares.
There were 189,000 small shareholders with less than 5000 shares.

Just these two smallest groups of shareholders is 522,000 shareholders.

Divide $500 SPP by 522,000 if every shareholder subscribed they would each only get $955 dollars worth of shares lol.

So:
a) I definately wouldn't be selling my existing shares on market in the hope that I can get the equivalent number of shares back in the share placement.
b) Unless they massively increase the $500m SPP, I very much doubt shareholders will get anything close to $30,000 allocation. My feeling is that those that only subscribe to a small qty will get their allocation, but those trying to get a larger allocation will have their allocation cut significantly.
