Summer cold fronts are Oceanic in nature, because that is what defines Cfb climates. It's not the ocean that allows cold fronts to reach Southern Australia, but departing high pressure ( very much a Cfb trait)
So we agree that it's not the ocean that allows these cold fronts to reach us. But should we really take Koppen's idea of a Cfb climate for granted though? Is it the "perfect" criteria? Like I said, many coastal climates have an oceanic influence to a degree anyway - from Vladivostok to New York. If these were more inland, they would be even colder. So does this mean that they are "oceanic climate" because they have an ocean moderation, despite their continental temperature range?
I would be honored if somebody finds me a climate similar to my dream climate:
Remember to put the LOWS in a high priority. They really matter (after the highs). Rainfall and sunshine hours can differ, but not too much.
You'll find pretty similar temperatures and rainfall amounts in highland Africa, but it's gonna be a dry winter distribution and without as large extremes in terms of temperature. https://en.m.wikipedia.org/wiki/Bulawayo#Climate

A really nice climate. Would prefer evenly spread rainfall that don't exceed 80mm to the least. But a good find there.
Am doing the 2002-2016 St. Petersburg averages because of curiousity. Remarkable July temps for this latitude I have to say: 23.8/16.1; that's even warmer than Stockholm's UHI for the same time. Some impressive heat there too, can't believe how a place by the Baltic Sea managed to have a 24.4C monthly mean in July 2010.
No month in Sweden has ever gone above 22C in mean and Stockholm is like 0.1-0.2C cooler than St. Petersburg in a normal July.
Impressive stuff!
Heathrow's 2002-2016 July average is 23.7/14.2. Barely different to the 81-10 average.

Yes, it is the ocean that allows these fronts to reach us. They're not warm enough to allow the formation of semi permanent high pressure zones during the warmer half of the year.
That's the essence of a Cfb climate - what happens during the warmer half of the year. Take that away and they are just C climates.
