National drive hosts Hughes and Langbroek caught their bosses off-guard last month when they announced they would defect to rival Hit Network in 2018.
It was announced soon after Laurie and Tilley's Melbourne breakfast show would be axed and replaced by ZM drive hosts Polly 'PJ' Harding and Jase Hawkins.
Confirming to news.com.au the shows had been yanked early, Laurie dubbed the decision "pretty offensive" and issued a word of warning to her replacements.
"I can only wish the new kids luck, they'll need it," Laurie told news.com.au, saying that the call blindsided them all.
"Obviously the company didn't trust any of us with a proper farewell, which is pretty offensive given the experience of the broadcasters involved.
"None of us has ever acted with anything less than full integrity, honesty and commitment which is unfortunately not what we received in return."
Hughes didn't return calls to news.com.au but announced the news to fans on Instagram on Friday, writing: "Call has come thru that this bunch of @hughesyandkate legends just had their last Drive shift ARN."
In a similar post on Facebook, Laurie wrote: "So it turns out today was our last day on KIIS FM in Melbourne. It's been a deeply weird two years, but our immediate team was so brilliant, they really made the daily grind survivable."
Despite the unpleasant end, Laurie remained upbeat about the future.
"It was a bit of a shock but I can't say I'm unhappy to be on holidays earlier than expected!" Laurie told news.com.au.
And on Instagram, Hughes wrote: "We've loved working with so many great people there and are pumped to start with @hitnetworkaus in 2018!"
Jase & PJ farewelled their ZM listeners earlier this month, as they made the move to Melbourne but will return to our airwaves in January 2018, continuing to host ZM's drive show from Australia.
