A further move to Camborne the next season saw attendances continued to flourish, rising to a peak of 3, 011 per game during the 2009–10 season. A move back to Penzance during the 2010–11 season heralded a steady decline in attendances, although as the county's only professional team the club still was easily the best supported. Despite their higher status, the Pirates continued to enjoy good relations with neighbouring clubs such as Redruth and Camborne, often playing home matches on Sunday so that supporters of those clubs can also attend games at the Mennaye Field.
The following season the Pirates again won their semi-final, beating Bristol over two legs, 45–24 at home and losing 29–18 away, resulting in a 63–53 win on aggregate. Pirates again however lost in the final, this time to London Welsh, losing 21–37 at the Mennaye and 29–20 away from home, 66–41 on aggregate. Following these highs, Pirates did not finish in the play-off places again, finishing between 6th and 9th in the subsequent seasons. They returned to the top four in the 2017–18 season, finishing 4th, however a restructure to the league for that season had seen the play-offs abolished, with 1st place being promoted to the Premiership automatically.
To be promoted to the Premiership a team must meet certain stadium requirements, and the capacity of the Mennaye Field is too small to meet these. Because of this, there have been many plans over the years for the Pirates to move into a new, larger stadium which meets these requirements to allow the Pirates to achieve their goal of promotion to the Premiership. The most concrete of these plans is the proposed Stadium for Cornwall, which would be home for both the Pirates and Truro City Football Club.  The Stadium For Cornwall has received funding from Cornwall Council, and is now only awaiting £3m of funding from the UK government before construction can begin, which is expected to be provided in Spring 2019.
However, it is my belief that we must try this venture". He expressed his personal happiness at the support expressed for the move and regarded it as a step towards a Premiership rugby club in Cornwall. Penzance & Newlyn RFC club badge. Joe Beardshaw wins line-out ball for the Pirates against Plymouth Albion Following a highly successful 2005–06 season, (when crowds were increased and the Pirates finished 3rd in Division 1), it was decided to relocate again and over the next two seasons the Cornish Pirates played their home rugby matches at Camborne RFC's recreation ground.
 The first stage is planned to have a capacity of 6, 000, which can be expanded to 10, 000 in phase two in the event of the Pirates being promoted. Supporters A number of promotions at the beginning of the 21st century saw the Pirates rise from south-west regional rugby all of the way up to the second division. The re-brand from Penzance & Newlyn to the Cornish Pirates for the 2005–06 season, along with relocating from Penzance to Truro, meant that the club was not only the highest ranked in the county but also the best supported, having doubled its supporter base in just over five seasons.
