We are renovating and would like to remove a wall section that sticks out into a bedroom, however I don't know how to tell if the corner beam is load bearing or not. It certainly looks pretty solid (see photo), but from looking underneath the house, it doesn't seem to be resting on top of any beams beneath, just straight onto the floor boards.
Do I need to get an engineer in?
Welcome to Workshop @EarlAJ. It's fantastic to have you join us. I hope you have plenty of fun on the site, and learn a thing or two from other community members.
I'm sure our resident engineering expert @BIM_Engineer could provide some assistance with your question about the beam.
I'm also keen to read more about what you are planning with your renovation.

Hi @EarlAJ,
Thanks again for joining Workshop. Just wondering if you could provide some more detail and photos so that @BIM_Engineer can assist as per his helpful message earlier in the week?
Jason
G'day @EarlAJ, a big welcome to the Workshop family, you're going to love it here, & we can learn from your adventures. 
@BIM_Engineer's put up his hand, & he's just the bloke to give you the answers in structural engineering.
From your photo, I'm wondering if it's been transposed by 90degrees, going by what look like being the cornices on the lefthand side. It may also be helpful when you send @BIM_Engineer your next batch of photos, if you remove the drywall at/near beam intersections etc.
Good luck with your renos, I'll be tuning in to see how it progresses.
@EarlAJ try to determine the load source first and then the load path to the crack
If you are able to carefully/safely inspect the roof frame/truss structure note down the position of struts/bearing for future reference.. this is easily done when building a new house from the ground before the ceiling goes in..great for identifying load sources->Potential future crack/hazards/etc
If you are unable to inspect the roof frame /truss get someone competent who can.
A roof structure inspection sketch plan is attached .HTH
@EarlAJ could post some photos of your roof setup, & your underfloor where the problem wall is mate? It'll help @BIM_Engineer make more sense of the situation.
From your original post, "We are renovating and would like to remove a wall section that sticks out into a bedroom, however I don't know how to tell if the corner beam is load bearing or not. It certainly looks pretty solid (see photo), but from looking underneath the house, it doesn't seem to be resting on top of any beams beneath, just straight onto the floor boards."
To me, it's kinda weird to me that it'd being resting just on the floorboards, without any subfloor support. 
Mind you, I saw a brick veneer home that was in the final stages of Gyprocking, it had a fibro column, that was for no other reason than for visual effect. I can say that with confidence, because there was a gap between the column & ceiling Gyprock, the only connection was via flimsy angle brackets, & tiny screws.
quote @BIM_Engineer:
"@EarlAJ have they compensated with larger joists or closer bearers beneath in the floor under the wall and which way do the structural support members span..?"
Very good points @BIM_Engineer, I'd hope that at the very least, the floorboard supports (structural support members) would run across the line of the wall in question, but that may kind of add doubt to whether it's a load bearing wall.
What are you thought?
