A hat if you wear glasses!
I'd suggest a light shell with good ventilation - having gone through a similar dilemma, and after good advice from here, I chose an Outdoor Research Aspire jacket.
http://www.campsaver.com/aspire-jacket-women-sIt It is Goretex, has TorsoFlo zips - hem to armpit, can be opened up either way.
Consider some of the men's gear too - esp for outerlayer where the fit isn't as vital - they have a much bigger range available. I also ended up getting a Medium sized men's Marmot Super Mica 247g (in green with blue zips) as I liked hubby's one so much. Has been great so far, even wore them as our shells in the Snowy's this easter (only light rain but v windy)
http://www.campsaver.com/super-mica-jacket-men-sLight merino T to to deal with the sweatiness - no cotton, or one of those light ventilated fitted synthetic cycling tops
If it's sunny I always wear one of those long sleeved light drip dry polyester travel/hiking shirts with a collar, and sleeves with rollups and the drawcords at the side so they look neat and non-bulky (Kathmandu makes good ones - get when on sale)
I use merino undies even in summer as they just don't have the sweaty problems other ones do, and have recently started to wear an icebreaker shaped merino bra (but not under a slim fitted T-shirt - I need a proper underwire bra for that as it shows more and I don't want any saggage factor. Then I just put up with an underwire T-shirt bra and sweat /sigh)
I only wear wollen socks, no cotton
Light synthetic zip off pants - if it's warm just get wet or wear them as shorts. Otherwise you can have the 'fun' of trying to find a pair of women's rain pants that fit....(see numerous threads with us having a bit if a whinge!)
I saw some heavier waterproof full zip ones with decent waist closures at Ray's outdoors for only $80 which looked promising, but have yet to try them on. Likey to heavy for SE Qld though.
Rainbirds etc will only keep light rain off, and in decent soaking rain they will wet through. They do help with wind though.
Waterproof electrical protection pouches for your phone and GPS (mine is a $10 Kathmandu one) , and similar larger one for map cover - Sea to Summit makes some. Osprey has one that rolls up and attaches to the front shoulder strap but I haven't tried that one so don't know how waterproof it it. The StS works fine.
Proetoction for camera equipmnt - I don't take my big one if it rains and just use a small camera or my phone, but I am sure the photographers here can give some good advice regarding keeping photographic equipment dry.
Pack cover and roll closure liner (ultrasil or cuben) - or use an Aarn pack which has fully waterproof inners
Ditch the mascara (unless you like the panda look!)
