Crowds were allowed to return from round 5 in very small groups, whilst larger crowds were allowed from round 8. Teams were also allowed to return to their own home grounds from round 8. On the 14th of August after winning against the New Zealand Warriors, Penrith broke the club record for their longest ever winning streak with their run of 9 straight wins, continuing to 14 straight wins on the 19th of September against the North Queensland Cowboys.
