SQ flight number on VA metal

[beast_man]

Hii guys,

Sorry if this has been asked earlier, but how can I book domestic flights in Australia on VA metal with a SQ flight number (so as to increase tier miles)?

I've tried booking via SQ website and can't seem to achieve it ...

Thanks in advance

I'm guessing they will only be available in conjunction with an SQ flight
