Write for The Shovel
The Shovel has a team of 4,000 full-time writers working in a satirical factory in Guangzhou, but we do also publish freelance submissions.
Got an idea? Follow the guidelines below:
The headline is the most important bit. You can just send us the headline if you like. We’ll know if it works or not.
The majority of the articles we publish are mock news-style, but we will consider other formats (like how-to guides, editorial style pieces, listicles, cartoons etc). Articles exposing the subversive communist undertones of Peppa Pig should be sent to The Australian.
Sending your ideas to us
Email your idea to hello@theshovel (dot) com (dot) au
In your subject heading write ‘Submission’ followed by your headline (or your best headline if you have multiple)
We try to get back to as many people as possible with a mock-polite rejection letter, but if we don’t, please don’t be offended. If you don’t hear from us within 2 weeks, assume that your piece won’t be published.
If you don’t want us to use your name, let us know.
By sending us your submission, you give us permission to edit your article and publish it in any format.
