Hi I’m new to using LORA

I’m in the process of setting up a LORA point-to-point system between a Raspberry Pi and an Arduino.

I’m happily using the AU915 band, and selected a single frequency to do the communication on.

Looking around I found the frequency plans that are listed on The Things Network website, which lists the uplink and downlink frequencies, at the below link.  
_(I understand that The Things Network is related to LORAWAN and not just LORA)_

Uplink:   
Channel MHz Hz SF  
1 916.8 916800000 SF7BW125 to SF10BW125  
2 917.0 917000000 SF7BW125 to SF10BW125  
3 917.2 917200000 SF7BW125 to SF10BW125  
4 917.4 917400000 SF7BW125 to SF10BW125  
5 917.6 917600000 SF7BW125 to SF10BW125  
6 917.8 917800000 SF7BW125 to SF10BW125  
7 918.0 918000000 SF7BW125 to SF10BW125  
8 918.2 918200000 SF7BW125 to SF10BW125  
9 917.5 917500000 SF8BW500

Downlink:   
Channel MHz Hz SF  
1 923.3 923300000 SF7BW500 to SF12BW500  
2 923.9 923900000 SF7BW500 to SF12BW500  
3 924.5 924500000 SF7BW500 to SF12BW500  
4 925.1 925100000 SF7BW500 to SF12BW500  
5 925.7 925700000 SF7BW500 to SF12BW500  
6 926.3 926300000 SF7BW500 to SF12BW500  
7 926.9 926900000 SF7BW500 to SF12BW500  
8 927.5 927500000 SF7BW500 to SF12BW500

This lists details the frequencies for communicating (up and down), as well as the spread factors and the bandwidth allowed.

**My question is** , if I’m using LORA for point-to-point communication, and I use one of these frequencies, do I need to follow the same parameters that are listed here?  
_i.e. if I use 917.2MHz I need to ensure my communication is between a spread factor of 7 and 10, with a bandwidth of 125kHz_

**And also** , if I’m using LORA for point-to-point communication only, there doesn’t seem to be any duty cycle restrictions (I understand that I don’t want to be hogging the airwaves though), what does the ACMA require?
