1977 NSL Cup

The 1977 NSL Cup was the first edition of the National Soccer League Cup, which was a national association football (soccer) knockout cup competition in Australia. All 14 NSL teams from around Australia entered the competition and it immediately followed the home and away season, as there was no final series. The competition was known as the Philips Cup under a sponsorship arrangement with Dutch company Philips.

It was proposed that all 14 NSL teams would enter along with other state league champions, but didn't feature state league teams for this edition until the next edition in 1978.

The NSL Cup was a knockout competition with 14 teams taking part all trying to reach the Final in October 1977. The competition consisted of the 14 teams from the National Soccer League.
