Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:03): I have a supplementary question. I refer the minister to further comments made by another South Australian Liberal MP, junior frontbencher Mr Briggs, who told 5AA in Adelaide, 'What work will be done on submarines in Australia will be done in Adelaide.' Given that this government refuses to rule out buying submarines from overseas, precisely what work is Mr Briggs referring to?
