A Full Plate of Shrimp...with Only One Shrimp?

I've been writing in my posts all week about the "plate of shrimp" analogy out of the movie Repo Man and I am still working on one more involving coincidence and Australia's biggest shrimp/prawn.
69, 2(0)17? Coincidence, or Just a Plate of Shrimp?

Then I see this story in the local news -

Forearm-sized prawn caught in Gulf of Carpentaria

"A huge leader prawn the size of a forearm and weighing 300 grams has been caught in the Gulf of Carpentaria.

Austral Fisheries northern division manager Andrew Prendergast said it was rare to catch a prawn weighing 300g.
"That's a pretty significant prawn," Mr Prendergast said
"They're not a target species of ours. 

We catch them incidentally and they're generally always bigger than the grooved or brown tigers.""

The weird thing also was my post is titled, 'The Longreach of Synchronicity', because it involves the Queensland town of Longreach ... as well as a big prawn.

I knew I should have written it sooner.

Shrimp on the Barbie

""Barbie" is Australian slang for barbecue and the phrase "slip a shrimp on the barbie", for Americans, often evokes images of a fun social gathering under the sun. 

Australians, however, invariably use the word prawn rather than shrimp.

Because the commercial was commissioned for broadcast in the United States, the change was made to limit audience confusion."
Why Would You Want to Throw a Shrimp/Prawn on the Barbie?
