Zumbo's Just Desserts review: incorrect tv-rating

The show has multiple instances of inappropriate language that does not fit with a TV-PG rating, including multiple counts of the f-word.
In order to comply with the ratings, which are there to ensure that people are watching age appropriate material, and so as not to by pass bad language through parental control limitations, the rating should either be changed, or the language (and subtitles) monitored.
