Hi @narayani,
Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you join us.
I'm sorry to say, It doesn't look like there's going to be a good way to repair this.
In other situations, such as How to repair burnt laminated benchtop? I have recommended using a combination of sanding, filler and paint to repair burnt benchtops, but unfortunately, the area that is burnt is quite large and the benchtop appears to be raised. Any repair you make to this area will be so large that it will be very obvious.
Unfortunately, the only way I see of getting a high-quality repair is to replace the benchtop.
You might like to have a look at our range of benchtops and our Custom Benchtop Installation service as options that might work for you.
Let me know if you have any further questions.
Jacob
