Are my bearer and joist spans correct for large deck?

Hi All

With the weather warming up, I'm getting ready to embark on my large outdoor deck. Hoping to have it finished ready for Christmas.

Just want to get some advise on my proposed stump/bearer and joist spans. Pretty confident in building the deck as Ive done a couple of years supervising a small tiny home company. Just was hoping to get an experts opinion to confirm my spans are correct. (pictured below)

 

NOTE: The top of the plan is where the deck will be connected to the house with a wailing plate. (hence the cantilever)

 

Thinking of using the following materials

 

135 x 19mm spotted gum decking

90 x 45mm treated pine joists

140 x 45mm double bearer

90 x 90mm treated pine posts

galvanised stirrups/high wind anchors

Evening @Scottydont85 

I am always nervous before starting a job then once Ive started I really ramp into enjoying it. Until the next stage or a part that is hard to work out or do comes up and then back to nervousness again :smile: Its like a roller coaster of fun lol

 

Looking forward to seeing it :smile:
