P&O Cruises Australia scraps select departures until 2022 Share P&O Cruises Australia will extend its pause in guest operations until the end of July. However, the line said it remains positive about a pathway for the cruise industry’s return to service. The current rolling pause will affect cruises scheduled from June 18th until the end of July. P&O Cruises is also cancelling voyages to Papua New Guinea and the Solomon Islands for the remainder of the year given the uncertainty around borders. This decision also affects this year’s Cairns season, where Pacific Explorer was to be based for two months from October.
