How about butcher block instead? IKEA and the big box stores sell it for countertops, the price is decent, and you won't have as many issues with buckling, water damage, or what to do with the edge as you would with the ply. If the edges of the ply get wet, or if any seam around a sink gets wet, the plywood will "blow" and you will have to replace it all, anyway.

We just stained our section fences with Wattle Ebony from Mitre 10. Was looking for a charcoal color too, not much flexibility in color options with stains from the shelves at store. We sprayed on, rather than brushing. Is cost a concern? One of our to be neighbours was doing there fences at the same time with paint, he said he used nearly 100L of paint for 2 coats, we used nearly 50L in 2 costs - had similar amount of fences. I've included photo of it after the 2 coats

Doesn't look worth it from that photo!

With the pantry being located where it is, it provides a opportunity to make it inbuilt and continue your bench top along. This would then provide more bench space and would make sure you are using that wall to its full potential. However for space and flow and to make your kitchen more ascetically pleasing, we would suggest keeping the island bench and making the appliances integrated. This provides opportunity to make that far wall a feature wall, which can be as simple as a blackboard or pictures, to making it a colour feature (depending on you cabinetry) or even to make it high class you could create a wood paneling feature. I hope this helps, either way you can add bonus features to your kitchen, you can create more storage and bench space with changing the pantry, or you could make a design feature out of that wall. It is up to you and where you design flair may take you. Good luck! :) If you would like to see these designs with a quote please call us on 03 423 9067 and we can organise a free one for you. Below are some pictures - in built pantry vs. feature wall. (making where the appliances are a low bench top with below cabinets). (goes beautifully with a black and white colour palette).
