It depends on which side of the fence you're looking from, but some of these records are outstanding, especially given one in particular occurred only last year.
Taking a deep dive into the record books, a lot can be revealed about a club and where it was placed in the competition at the time.
For Canterbury-Bankstown in the 1930s, it was a dark and dour time.
In 1993, Parramatta put together a decent year, but there was one day in August they'd like to forget.
The same can be said for the Wests Tigers in July last year, who along with a bottom-place finish, copped the third biggest loss in Australian Rugby League history, going down to the North Queensland Cowboys 74-0.
Margin | Winners | Losers | Score | Date |
85 | St. George | Canterbury-Bankstown | 91-6 | 11 May 1935 |
80 | Eastern Suburbs | Canterbury-Bankstown | 87-7 | 18 May 1935 |
84 | North Queensland Cowboys | Wests Tigers | 74-0 | 1 July 2023 |
70 | Parramatta Eels | Cronulla-Sutherland Sharks | 74-4 | 23 August 2003 |
68 | Canberra Raiders | Parramatta Eels | 68-0 | 22 August 1993 |
In terms of the biggest losses in the NRL Finals, the Brisbane Broncos hold that title in 2019.
Coming up against the dominant Parramatta Eels, the Broncos struggled to defend the offensive powerhouse, conceding 58 points while failing to score themselves.
