A bit wary

Sounds like a scam to me too. The government wouldn't text you out of the blue, they'd contact you by post instead, and there would be government website pages to visit giving you all the information you need. If you were to visit the website in the text, most likely it would ask you to hand over your bank details and other private information in order to receive the payment.
