Tickets for Splendour In The Grass 2016 went on sale this morning and sold out within a matter of hours. For those lucky enough to score passes, now begins the long, laborious process of Splendour prep.

In addition to making sure you have all the necessary camping equipment, for some this will involve organising transportation to the festival’s Byron Bay site. However, Splendour organisers want you to be conscientious with your choices.

Specifically, organisers would prefer you steer clear of campervans emblazoned with sexist slogans. As FasterLouder reports, Splendour officials have issued a specific warning to punters via their official website.

“If you’re booking a campervan, please steer clear of sexist slogans! You know who you are. It’s 2016. Get with the program.” Whilst it hasn’t been confirmed, many speculate the warning is aimed at patrons of Wicked Campers.

The company offer super-cheap campervans, often decorated with gaudy street art, usually bearing references to drugs or sexual innuendo, which many consider to go well beyond the realms of just plain bad taste.

As the blog Questions For Us details, the slogans on Wicked Campers vehicles range from crass to downright rapey. In fact, in 2014 company chief John Webb removed an offensive slogan from his vans in the wake of a petition that garnered 110,000 signatures.

According to FasterLouder, at least two acts booked for recent Splendour iterations have worked with the company. Dune Rats, who performed at Splendour 2015, have promoted the company and 2016 act Kim Churchill was featured in a promo for the company early last year.
